It's all videos so the game will eventually get pretty huge like my other game. I will look into that though. I will try some video exports to see how much bigger it gets. I will try upsampling too but usually it comes out kinda blurry. I will try though. On steam the file size doesn’t really matter.
Update:
I tried upscaling some videos and I don't see the difference between just maximizing the game. It makes the files 3 times bigger. Probably the only way to get it to change anything would be to re-export all videos. I tried that too and my software coughed at me and just didn't do it. I have pretty decent hardware too.
